Many people think it is safe to use a cell phone while they are driving. Yet Scores of studies suggest that real multitaskers - those who can carry out multiple   tasks equally well, make up just 2 per cent of the population. More surprisingly, the so-called "supertaskers" actually have differently structured brains to the other 98 percent.  The brain areas that make supertaskers differ from the rest of the population are the same parts that are most different between humans and nonhuman primates  , according to David Strayer, director of the applied cognition lab at the University of Utah. Scientists are unsure of the reason why some brains are different. In fact, we could all benefit from doing just one task at once. In most of us, scientists have located a "bottleneck in the brain" that may explain why we find it hard to do two things at once. The problem appears to be caused by a logjam of nerve messages. Faced with two almost simultaneous   tasks less than 300 milliseconds apart, the brain's ability to deal with the second one slows down. The neural   response to the second task was postponed until the response to the first was completed. This means that with e-mails, phone calls, text messages and online social media all competing for our attention, often against a background of television, radio or music, our brains can reach information overload.  Scientists made the discovery after scanning the brains of volunteers attempting to multitask on a computer. The task was deliberately designed to involve the use of different senses and  _ responses. Dr Rene Marois, one of the neuroscientists who carried out the experiment at Vanderbilt University in Nashville, Tennessee, said: "Our research offers neurological evidence that the brain cannot effectively do two things at once." The next step, the neuroscientists say, is finding out "why these areas cannot process two tasks at once." The researchers tried to find out the difference between   _   brain structures. A) different supertaskers' B) supertaskers' and ordinary people's C) humans' and nonhuman primates' D) supertaskers' and nonhuman primates'

I remembered that when I was a little child, I used to look for Sunday of the week. Yes, I was so looking forward to an adventure. Now, I still have a strong _ for buses. I used to wonder where those gigantic   buses finally stopped. On sunshine Sundays, that's my adventure times. He took me to the bus stop. Time passed, while I was growing impatient, he was smiling, as he always does. It was really not that easy to get on a bus as often as we do today. I was so worried that the bus driver would have missed us. I waved my hands so high with all my strength. I looked hopefully at him. He didn't move at all. He was still standing. It seemed that the late and infrequent coming of the bus wasn't any trouble to him at all. He took my hand. We managed to find seats on the upper deck. I was so excited. Only sitting beside the windows made me happy. Looking at the rewinding buildings, streets and people through windows from a higher ground was so much fun. Then, he was sitting peacefully by me and whispered to me where the bus finally would stop. I was curious about what would be the next stop of our destination as much as what really means something to him. That is me. I know now. I am all he cares. He wants me to be happy, as he always does. That's the strong bond between father and son. Childhood, naive  and precious, you showed me the world and the way I look at the world. I am so grateful for your presence in my life. Thanks, you are so wonderful! Who is "he" throughout the text? A) The brother of the writer. B) The son of the writer. C) The father of the writer. D) A bus driver.
